Clearing Translation Table Entries
In addition to the aging mechanism, the software allows you to manually clear entries from the NAT table. The
software provides the following clear options:
• Clear all entries (static and dynamic)
• Clear an entry for a specific NAT entry based on the private and global IP addresses
• Clear an entry for a specific NAT entry based on the IP addresses and the TCP or UDP port number. Use this
option when you are trying to clear specific entries created using the Port Address Translation feature.
To clear entries, use the following CLI method.
USING THE CLI
To clear all dynamic entries from the NAT translation table, enter the following command at the Privileged EXEC
level of the CLI:
BigIron# clear ip nat all
Syntax: clear ip nat all
To clear only the entries for a specific address entry, enter a command such as the following:
BigIron# clear ip nat inside 209.157.1.43 10.10.10.5

Table 20.2: CLI Display of NAT Statistics (Continued)
Displays...
Lists session statistics. NAT uses the session table for managing the
translations.
• Total – The total number of both used and available internal
session resources.
• Avail – The number of free internal session resources.
• NAT – The number of internal session resources currently used
by NAT.
For information about the session table, see "Layer 4 Session Table"
on page 15-7.
A global IP address.
The last inside local IP address to use the global IP address.
The number of packets send out for this NAT global IP address from
the inside to the outside network.
The number of bytes send out for this NAT global IP address from the
inside to the outside network.
The number of packets received from the outside network to the
inside network for this NAT global IP address.
The number of bytes received from the outside network to the inside
network for this NAT global IP address.
The number of session resources in use for the translation.
Note: If the value is 0, then translation is not taking place. Check your
configuration. For example, make sure you have enabled both inside
NAT (on the interface to the private addresses) and outside NAT (on
the interface to the Internet).
